The drive motor drives the rotating shaft to rotate, and the grinding roller rolls on the grinding disc to grind the raw materials. The rectangular brushes and claws clean the grinding disc, and the arc-shaped brushes clean the grinding roller, preventing the powder from sticking together and ensuring grinding effect and efficiency.

[0007] Preferably, a feed hopper is installed on the top side of the grinding cylinder, and a discharge pipe is connected to the bottom side of the grinding cylinder. A valve is installed on the outside of the discharge pipe. The raw material enters the grinding cylinder through the feed hopper.

A driven gear and a driving gear are mounted on one end of each connecting shaft, and the driven gear and the driving gear mesh with each other. A support base is mounted on one side of the feed hopper, and a crushing motor is installed inside the support base. One end of the connecting shaft is connected to the output end of the crushing motor. The crushing motor drives the connecting shaft to rotate. Through the meshing of the driven gear and the driving gear, the two crushing rollers rotate relative to each other, pre-crushing the raw materials entering the feed hopper and improving the subsequent grinding efficiency.

[0009] Preferably, a dust collection box is installed on one side of the grinding cylinder, a negative pressure motor is installed inside the bottom of the dust collection box, three fan blades are installed at the output end of the negative pressure motor, an exhaust pipe is connected to the bottom of the dust collection box, a conveying pipe is connected to the top of the dust collection box, one end of the conveying pipe extends into the interior of the grinding cylinder and is connected to a dust suction hood, the dust suction hood is located at the top of the grinding cylinder, the negative pressure motor drives the fan blades to rotate, creating a negative pressure inside the dust collection box, and the dust generated during the grinding process is sucked into the dust collection box through the dust suction hood and the conveying pipe, realizing the centralized collection of dust and reducing environmental pollution.

[0010] Preferably, three connecting rods are equidistantly installed on the top side of the dust collection box, and limit blocks are installed on the bottom side of each connecting rod. A filter cartridge is slidably installed on the outer side of the connecting rods. The filter cartridge is V-shaped, and the top radius of the filter cartridge is less than or equal to the inner diameter of the dust collection box. Three springs are fixed between the top side of the filter cartridge and the dust collection box, and the springs are sleeved on the outer side of the connecting rods. A plug is movably installed inside the bottom side of the filter cartridge. An outlet is installed on the outer side of the middle end of the dust collection box through a hinge.

[0012] The advantages of this utility model are:

[0013] 1. After the drive motor of this utility model is started, the rotating shaft rotates at high speed. During the grinding process, the top surface of the arc-shaped brush contacts the grinding roller and scrapes off the powder material adhering to the surface of the grinding roller during the rotation of the grinding roller, so as to avoid the material from clumping and affecting the grinding efficiency. At the same time, the rectangular brush and the claw are in close contact with the top surface of the grinding disc to clean the powder residue on the surface of the grinding disc. The claw-shaped structure of the claw is used to scrape off the material clumps that are adhered firmly, ensuring that the surface of the grinding disc is clean and improving the grinding effect.

[0014] 2. This utility model draws the dust generated during the grinding process into the dust collection box. After the dust-laden airflow enters the dust collection box, it flows upward through the filter cartridge to intercept the dust. A spring is sleeved on the outside of the connecting rod.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-4As shown, a powder raw material grinding device includes a grinding cylinder 1. A grinding disc 2 is installed on the inner wall of the top of the grinding cylinder 1. The grinding disc 2 has several through holes. A drive motor 3 is installed on the bottom side of the grinding cylinder 1. A rotating shaft 4 is installed at the output end of the drive motor 3. A rod hole is opened at the center of the grinding disc 2. The top of the rotating shaft 4 is movably connected through the rod hole. Two support rods 5 are symmetrically installed on the outer side of the top of the rotating shaft 4. A grinding roller 6 is rotatably installed on the outer side of the support rods 5. An arc-shaped brush 7 is installed on the outer side of the rotating shaft 4 directly above the grinding roller 6. The arc-shaped brush 7 is in contact with the top side of the grinding roller 6. Two rectangular brushes 8 are symmetrically installed on the top of the rotating shaft 4. A claw 9 is installed on one side of the rectangular brush 8. The claw 9, the rectangular brush 8, and the grinding roller 6 are all in contact with the top side of the grinding disc 2. The arc-shaped brush 7 and the rectangular brush 8 are both hard-bristled brushes.

[0024] A feed hopper 10 is installed on the top side of the grinding cylinder 1, and a discharge pipe 11 is connected to the bottom side of the grinding cylinder 1. A valve 12 is installed on the outside of the discharge pipe 11.

[0025] Two connecting shafts 13 are rotatably mounted through the two sides of the feed hopper 10. Crushing rollers 14 are mounted on the outer side of each connecting shaft 13. A driven gear 15 and a driving gear 16 are mounted on one end of each connecting shaft 13, and the driven gear 15 and the driving gear 16 mesh with each other. A support base 17 is mounted on one side of the feed hopper 10. A crushing motor 18 is installed inside the support base 17. One end of the connecting shaft 13 is connected to the output end of the crushing motor 18.

[0026] Three support legs 31 are equidistantly installed on the bottom side of the grinding cylinder 1. A control panel 32 is installed on the outside of the grinding cylinder 1. The control panel 32 is electrically connected to the electrical components inside the device. The control panel 32 is used to electrically connect the electrical components inside the device. During operation, in practical applications, the characteristics of the powder raw material cause it to easily stick to the outside of the grinding disc 2 or grinding roller 6 during the grinding process. This will prevent the stuck raw material from being fully ground, which will have an adverse effect on the quality of the product. After the crushing motor 18 is started, it drives one of the connecting shafts 13 to rotate through the output shaft. The drive gear 16 on the connecting shaft 13 rotates accordingly. The drive gear 16 meshes with the driven gear 15, driving the other connecting shaft 13 to rotate in the opposite direction, so that the two crushing rollers 14 rotate relative to each other. The powder raw material is poured in from the top of the feed hopper 10 and enters the gap between the two crushing rollers 14. Since the surface of the crushing roller 14 has teeth, the large pieces of raw material are crushed into smaller particles through squeezing and shearing action, which reduces the load for subsequent grinding and improves the grinding efficiency.

[0027] After the drive motor 3 starts, the rotating shaft 4 rotates at high speed, driving the outer support rod 5, grinding roller 6, arc-shaped brush 7, rectangular brush 8, and claw 9 to rotate synchronously. The two grinding rollers 6 are connected to the rotating shaft 4 through the support rod 5. As they rotate with the rotating shaft 4, they roll tightly against the inner wall of the grinding disc 2 due to centrifugal force. The surface of the grinding roller 6 rubs against the grinding surface on the top surface of the grinding disc 2, further grinding the pre-crushed raw material particles into fine powder. During the grinding process, the arc-shaped brush 7 contacts the top surface of the grinding roller 6, scraping the powder material adhering to the surface of the grinding roller 6 as it rotates. The grinding disc 2 is cleaned by the bristles of the rectangular brush 8 to remove residual powder, while the claw-shaped structure of the claw 9 scrapes off firmly adhered material clumps, ensuring the surface of the grinding disc 2 is clean and improving the grinding effect. Unqualified material remains on the grinding disc 2 for further grinding. The fine powder after grinding falls into the bottom of the grinding cylinder 1 through several through holes on the grinding disc 2. After accumulating to a certain amount, the valve 12 of the discharge pipe 11 is opened, and the fine powder is discharged through the discharge pipe 11.

[0028] Please see Figure 1 , 2 As shown in Figure 5, a dust collection box 19 is installed on one side of the grinding cylinder 1. A negative pressure motor 20 is installed inside the bottom side of the dust collection box 19. Three fan blades 21 are installed at the output end of the negative pressure motor 20. An exhaust pipe 24 is connected to the bottom end of the dust collection box 19. A conveying pipe 22 is connected to the top side of the dust collection box 19. One end of the conveying pipe 22 extends into the interior of the grinding cylinder 1 and is connected to a dust suction hood 23. The dust suction hood 23 is located at the top of the grinding cylinder 1.

[0029] Three connecting rods 25 are equidistantly installed on the top side of the dust collection box 19. Limit blocks 26 are installed on the bottom side of each connecting rod 25. A filter cartridge 27 is slidably installed on the outer side of the connecting rods 25. The filter cartridge 27 is V-shaped, and its top radius is less than or equal to the inner diameter of the dust collection box 19. Three springs 28 are fixed between the top side of the filter cartridge 27 and the dust collection box 19, and the springs 28 are sleeved on the outer side of the connecting rods 25. A plug 29 is movably installed inside the bottom side of the filter cartridge 27. An outlet 30 is installed on the outer side of the middle end of the dust collection box 19 via a hinge. During operation, dust is easily dispersed with the airflow during the grinding of the powder raw material, causing not only material waste but also pollution of the working environment. Therefore, during the grinding process, a negative pressure motor 20 is started, which drives the fan blades. 21. High-speed rotation creates negative pressure inside the dust collection box 19. The dust suction hood 23 at the top of the grinding cylinder 1 is connected to the dust collection box 19 through the conveying pipe 22, drawing the dust generated during the grinding process into the dust collection box 19. After the dust-laden airflow enters the dust collection box 19, it flows upward through the filter cartridge 27. The filter cartridge 27 has a "V" shaped structure to intercept the dust. Clean air is discharged through the exhaust pipe 24, reducing dust pollution in the workshop. The spring 28 is sleeved on the outside of the connecting rod 25. The filter cartridge 27 generates high-frequency micro-vibration under the impact of the negative pressure airflow, causing the dust attached to the filter screen to fall off and slide down the inner wall of the filter cartridge 27 to the bottom. When the dust accumulates to a certain amount at the bottom of the dust collection box 19, the hinge cover of the outlet 30 is opened, and the plug 29 at the bottom of the filter cartridge 27 is pulled out. The dust is discharged through the outlet 30 and can be recycled, improving the utilization rate of raw materials.

[0030] Working principle: After the crushing motor 18 starts, it drives one of the connecting shafts 13 to rotate through the output shaft. The drive gear 16 on the connecting shaft 13 rotates accordingly. The drive gear 16 meshes with the driven gear 15, driving the other connecting shaft 13 to rotate in the opposite direction, so that the two crushing rollers 14 rotate relative to each other. The powdered raw material is poured in from the top of the feed hopper 10 and enters the gap between the two crushing rollers 14. Since the surface of the crushing rollers 14 has toothed patterns, the large pieces of raw material are crushed into smaller particles through squeezing and shearing action, which reduces the load for subsequent grinding and improves the grinding efficiency.

[0031] After the drive motor 3 starts, the rotating shaft 4 rotates at high speed, driving the outer support rod 5, grinding roller 6, arc-shaped brush 7, rectangular brush 8, and claw 9 to rotate synchronously. The two grinding rollers 6 are connected to the rotating shaft 4 through the support rod 5. As they rotate with the rotating shaft 4, they roll tightly against the inner wall of the grinding disc 2 due to centrifugal force. The surface of the grinding roller 6 rubs against the grinding surface on the top surface of the grinding disc 2, further grinding the pre-crushed raw material particles into fine powder. During the grinding process, the arc-shaped brush 7 contacts the top surface of the grinding roller 6, scraping the powder material adhering to the surface of the grinding roller 6 as it rotates. The grinding disc 2 is cleaned by the hard bristles of the rectangular brush 8 to remove residual powder from the surface of the grinding disc 2, while the claw-shaped structure of the claw 9 is used to scrape off firmly adhered raw material clumps, ensuring the surface of the grinding disc 2 is clean and improving the grinding effect. Unqualified raw materials continue to be ground on the grinding disc 2. The fine powder after grinding falls into the bottom of the grinding cylinder 1 through several through holes on the grinding disc 2. After accumulating to a certain amount, the valve 12 of the discharge pipe 11 is opened, and the fine powder is discharged through the discharge pipe 11.

[0032] During the grinding process, the negative pressure motor 20 is started, which drives the fan blade 21 to rotate at high speed, creating a negative pressure inside the dust collection box 19. The dust suction hood 23 at the top of the grinding cylinder 1 is connected to the dust collection box 19 through the conveying pipe 22, and the dust generated during the grinding process is sucked into the dust collection box 19. After the dust-laden airflow enters the dust collection box 19, it is carried upward through the filter cartridge 27. The filter cartridge 27 has a "V" shaped structure to intercept the dust. The clean air is discharged through the exhaust pipe 24, reducing dust pollution in the workshop. The spring 28 is sleeved on the outside of the connecting rod 25. The filter cartridge 27 generates high-frequency micro-vibration under the impact of the negative pressure airflow, causing the dust attached to the filter screen to fall off and slide down the inner wall of the filter cartridge 27 to the bottom. When the dust at the bottom of the dust collection box 19 accumulates to a certain amount, the hinge cover of the outlet 30 is opened, and the plug 29 at the bottom of the filter cartridge 27 is pulled out. The dust is discharged through the outlet 30 and can be recycled, improving the utilization rate of raw materials.
